Quick scanning showed that /etc/inittab has the "xdm" section commented out. My guess is that the plan is to move to "gdm" or similar for the session management, and it just was not done yet.
xdm is now managed by /etc/rc.d/init.d/xdm, which runs only in runlevel 5.
So you are saying that even if I say that I want graphical startup, the installer is not switching the default runlevel ? Or how is this supposed to be handled ?!
OK I think we were on the wrong page (I didn't really understand the question). Matt says this is fixed.
